No. The Deal prices are good starting on an items first day, through the end of the event or whenever it sells out.
For example, if you want the deal from day one, the sale price is good from 11/20/20 through 12/1/20 or until it sells out. If you want the deal for day 10, the sale price is good from 11/28/20 through 12/1/20 or when it sells out.
